A diagnosis device includes: an estimation unit that is configured to estimate a deterioration state of a secondary battery on the basis of an output of a sensor mounted in the secondary battery supplying power for running driving of a vehicle; a deriving unit that is configured to derive an index value representing validness of data used for estimating the deterioration state; and a request unit that is configured to request an external charger for supplying power to the secondary battery to perform a specific charging/discharging operation in a case in which the index value derived by the deriving unit is equal to or smaller than a predetermined value.
